HER/BEST, F WHEELING, WEST VIRGINIA, ASSIGNOR T0 THE CONSOLI- DATED EXPANDED METAL COMPANIES, OF i'l-I1'lI!]'.I.`L\If(3rJ WEST VIRGINIA, A C`ORPO' RATION OF WEST VIRGINIA METALLIC SCREEN Y Application filed April 12,

rllhis invention relates to metallic screens, guards, grilles, grating, and the like, and it is especially useful Where the screen, after assemblage, is to be galvanized.

One of the primary objects of the invention is the provision of a simple and effective screen construction.

Another object of the invention is to provide a screen which may be subjected to a galvanizing bath Without retaining any material excess of the spelter When removed.

I accomplish the foregoing, together With such other objects and advantages as may hereinafter appear, by means of a construcs tion which I have illustrated in preferred form in the accompanying drawings, Where- 1n- F ig. 1 is a more or less diagrammatic side elevation of a screen embodying my invention.

Fig. 2 is a fragmentary side elevation of a detail of the invention drawn on an enlarged scale. f l Fig. 3 is a section taken on the line 3`3 of Fig. 2.

Referring noW to Fig. l, the screen, guard, grille, or the like, is composed of a frame A in which is carried screening, such as metallic fabric or lath 7.

The frame is composed of metallic edging 8 which is approximately in the form of a U in cross section, the base 9 of the U being enlarged and being in the form of a bulb. Suitable lengths of this edging are secured to gether at the corners of the frame by pairs of clips or brackets 10 which have curved portions 11 adapted to fit the bulb and Web portions 12 adapted to abut against the legs of the U. The pairs of clips at each corner are secured together, as by means of rivets 13 which also serve to engage the edge portion of the metallic fabric 7. The clips are provided with run-out apertures or holes 14 preferably located at the apex of the clips. The assembled structure is rigid and strong, but relatively light, and When it is dipped, as into a galvanizing or painting bath, and removed, the excess spelter or other coating material will run out of the openings 14, thus preventing the hollow edging from re- 1928.

maining filled With the coating material which would beobjectionable both from the standpoint of economy as Well as the standpoint of Weight.

What I claim is 1. A screen, adapted to be dipped and co-ated, comprising .hollovv framing, and metallic fabric having its edges extending therein, the framing having run-out openings for the coating material.

2. A screen comprising a frame composed of lengths of U-edging, brackets for frame corners having run-out openings, and metallic fabric having its edges extending in the edging, the assembled structure being adapted to be galvanized.

3. A screen comprising a frame composed of lengths o-f U-edging, brackets for frame corners having run-out openings, and metallic fabric having its edges extending in the edging', the assembled structure being adapted to be galvanized. y s

4. A screen comprising a frame composed of lengthsof Uedging, having the base portion in the form of a bulb, brackets for the frame corners on each side of the screen, said brackets having portions fitting the bulb, means for securing the pairs of brackets together, and metallic fabric having itsedges extending in the edging and engaged by the securing means, said frame having run-out openings and the assembled structure being adapted to be galvanize In testimony whereof I have hereunto signed my name.
